'EQ ALL WHOM I'l IHA- Y CONCERN: A

Be it known that I, H. D. PALMER, of Cleveland, in the county of Cuyahoga, and State of Ohio, have invented a new and Improved Cover for the Rollers of Wring'ing Machines; and I do hereby declare that the following isa full, clear,'and eiract description thereof, reference being had 'to thciaccompanying drawings, making a part of this specification, in whieh Y Figure 1 ,is'al view-of the exterior'of :pai'r of rollers` cavern Figure 2`is a diametrical section through a pair of i'ollers, showing themethod of coveringthem.

' -ll`igure 3 is a transverse section throughl the same.

Figure-shows the method of covering a slotted shaft. i

Figure 5 is an enlarged cross-section of one of the rollers.

Similar letters'of reference indicate corresponding parts in the several figures.

In the construction, of rollers for wringingmachines,'and other machines operating upon the same principle, it is desirable to' employ vulcanized India rubber as the covering; but in consequence of the great strain to which such rollers are subjected, the methods 4hitherto adopted of` applying the' India rubber .tol the shafts do not4 aiford suiiicient strength to eil'ectua-lly resist such strain. To effect a more perfect connection of the covering of a roller-.shaft with such shaft, the nature of my invention consists inY employing a slottedv or sectionalshaft,

an'd'so constructing the covering that some portionfof it will extend through such `shaft, und thus prevent the latter from working loose or turning within its covering, as will be hereinafter described.

The shaft uponlwhich the covering is applied maybe made of two or more long/itudirkul sections, which are provided with screw caps on their extremities, or, what-,isA preferable, Iv'use a sh ft, Alxiaving a longitudinal slot, a, through it, which slot may extend the entire length which it isdesired t; over the`shaft, as shown in figs. 2 and 4. If desirable, morethan one slot may be made, but forfall practical purposes, and'for the purpose of setting forth my inventionfthe'single slotted roller shaft A will answer.` Upon such a roller I- apply a. cloth covering, 6, which is passed around the roller or shaft, and its ends carried .through the slot a, througlr said shaft, and suitablyfastened,by..cement or otherwise. TheI shaft'thus covered with canvas, cloth, or other fabric or substanceswhi'ch may be found' Jtoanswerthe best purpose, is now covered with vIndia rubber, and this latter substance canized directly uponsaid shaft, thus completing the roller. Instead of vulcauizing the rubber coveringupon their shafts, these coverings maybe made upon a sectional shaft, or upon sections of a shaft, after w the sections can be withdrawn, leaving-the coveriughollow, with a central divisie/mc, in its centre, as shown in iig. v5. These hollow coverings can b plied to two semi-cylindrical sections, and the latter secured at their ends by means of journalf'screw caflin any other suitable manner. It is the 'divisional portion c of the covering of the shaAthat preven sl `4is covering from slipping'or working loose; the Indiav rubber which surrounds said. shaft w 4iiriilyattach itself to the lcovering a, but will not adhere with sufcient tenacity to `vthe smooth metal; consequently, byhaving the irst covering z surround and pass through a slot in the roller shaft, or between the abutting 'surfaces of 'a sectional shaft, the outer covering will not be liable to wear loose. -flhe first covering a may: be'made of canvas cloth, of wire cloth, or of any substance to which the India rubber will attach itself, and which will possesI strength and durability. Y

Having thus described my inveutionl,uwhat I claim as new, and desire to secure by Letters Patents, is-

1. The rubber o1' other non-absorbent cloth, supported coverings,]3,' I; c, whether they are made or vulcanized directly upon the shaft ns described, or separately, and afterward applied to thc shaft, substantially as described. v n' y 2. Securing a cover, B, upon a slotted or sectional shaft, by means of a divisional cloth or canvas connection,`c, vthe termini of which underlap upon the shaft, as shown, substantially as described.

H. D. PALMER.
